There aren’t many scenes in cinema that have reached a level as iconic as Anita Ekberg’s dip in the Trevi Fountain in Fellini’s La Dolce Vita. Countless tourists flock to the fountain every year, and if they don’t jump in themselves, there are probably two good reasons for this. One is that the local council now puts bleach in the water, and the other is that the scene wasn’t really filmed at the real fountain.

Instead, the Trevi Fountain scene was shot at a recreation of the fountain on a lot at Rome’s Cinecitta studios, a few miles south of the real thing.

If this made the filming more convenient, it didn’t make it any more pleasant for the two stars: the scene was shot in winter, and Marcello Mastroianni needed both a wetsuit under his tuxedo and a bottle of vodka to prepare himself for the icy waters of the fountain, while Ekberg was wearing thigh-length waders under her dress.
